....

Seeing her sister constantly acting up, Sona decided to change the subject.

"Onee-sama, why did you suddenly come to the human world? Don't you have a lot of work to do in the Underworld?"

"Heehee! The Three Factions' Peace Conference between Devils, Angels, and Fallen Angels is coming up soon, right? I'm in charge of foreign affairs for the Underworld, so I have to attend the talks," Serafall replied with a giggle.

"So, for a while, your Onee-sama will be staying in Kuoh Town, That means I can live with Sona-chan!"

"!!!"

"No! Onee-sama, you can't stay with me. I'll find you a place to stay right away!" Sona exclaimed, her face pale with alarm.

The thought of Serafall's eccentric behavior filled Sona with dread.

"Hehe, it's no use. I already know where Sona-chan is living!"

Serafall said, blinking innocently.

Just then, I interjected, "Hmm, I think my house is already full. We haven't finished expanding it yet. Where would Serafall-sama stay?"

Hearing this, Serafall's eyes widened in shock.

"Eh? What do you mean? Are you and Sona-chan living together?"

"That's right! and not just Sona. Everyone from the Student Council and Rias's peerage are also living at my house."

"So, who are you going to share a room with?"

"L-living... together..." Serafall murmured, her face turning pale.

She looked like a cat whose fur was standing on end, then she bared her teeth and roared, "Waaaaaah! You hateful human, how dare you steal my cute Sona-chan!"

"..."

Seeing Serafall's reaction, I was speechless.

'This sis-con is a little terrifying!' I thought to myself.

Sona quickly stepped in between me and Serafall, sighing helplessly. "Onee-sama, please stop making a scene. Otherwise, I'll be really angry!"

Hearing Sona's words, Serafall froze as if struck by lightning.

Then, she retreated to a shady corner, squatting down, drawing circles with her finger, and whimpering.

"Boo-hoo-hoo, Sona-chan is mad at me... She doesn't want me anymore..."

Seeing this childish Maou, the Student Council members exchanged helpless glances.

"I'll go talk to her," I said, smiling at the others.

"Kyoya..." Hearing my words, Sona was taken aback.

"Don't worry, it'll be fine," I reassured her, walking towards Serafall.

Hearing my footsteps, Serafall looked up at me happily, but when she saw it was me, her expression fell again. She pouted and said, "Hmph, are you here to gloat?"

Seeing Serafall acting like a child, I squatted down beside her and smiled. "Serafall-sama, Sona didn't mean it. She's still your beloved little sister. Look, she's is looking at you right now."

"So, cheer up. Give me a smile."

Serafall turned her head and saw Sona looking at her with concern.

Immediately, she jumped up, smiling, and said to me in a proud tone, "Hmph! I knew it. Sona-chan loves me the most!"

I quickly chimed in, "Of course! Sona likes Serafall-sama the most."

Hearing my flattery, Serafall looked very pleased with herself, but then she added, "Of course. But even if you praise me like that, I won't give Sona-chan to you!"

"Oh, That would be terribly rude of me."

Although I spoke respectfully, that wasn't what I was thinking.

'Serafall, just wait. Once I complete the task, not only will Sona be mine, but you'll be mine too!! Hehehe...'

Then, I smiled mysteriously and said to Serafall, "By the way, I heard that Serafall-sama likes to dress up as a magical girl. I happen to have an exquisite magical girl gift that I'd like to give you! I'm sure you'll love it."

Serafall's eyes widened in surprise.

She couldn't believe I knew about her hobby and had even prepared a gift for her.

The thought of an exquisite magical girl outfit filled her with excitement.

"Really? Are you really giving me a magical girl gift? In that case, I'll reluctantly accept it!"

As soon as I finished speaking, a delicate magical girl outfit appeared in my hand.

The instant she saw the outfit in my hand, Serafall's eyes lit up, staring at it intently.

"Oh my... It's so beautiful! I've never seen anything like it!"

Then, Serafall took the magical girl outfit and held my hand. "You're not so bad after all. Thank you for the wonderful gift"

"And you saved Sona-chan before. In that case, I can consider sharing Sona-chan with you. How about it? I'm generous, right?"

Hearing this, my thoughts momentarily froze.

'What a dedicated sis-con! But to think she'd sell out her own sister after being bribed with a magical girl outfit!'

This turn of events left me speechless.

But even more tragic was that Sona, who had been curious about what I was discussing with her sister, overheard Serafall's outrageous statement. Her head was steaming, and she was gritting her teeth in frustration!

'What do you mean, share me? Am I a cake to be sliced up and shared...' she thought, fuming.

Seeing that Serafall had accepted the gift, I continued to tempt her.

"Serafall-sama, why don't you change into this magical girl outfit now? Then I can take some photos or videos of you. We could even organize a magical girl TV show."

"And we can post the photos and videos online, and even broadcast your magical girl show on TV. That way, the whole world will know how cute and beautiful Serafall-sama is."

"Maybe even the angels and devils of the Three Factions will think that Serafall-sama is the most beautiful, even more beautiful than the Archangel Gabriel!"

"What do you think, Serafall-sama? Are you interested?"
